Classic Did an update go through today? My game is unplayable due to less than 10fps

I was playing a few hours ago then got off. I just got back on and and I think something downloaded. My framerate now is at like 10fps. Prior, it was at 144 on ultra 1440p with raytracing.. Does anyone know how I can fix this?Edit: I downloaded an Nvidia update to my GPU right before I last turned off my PC. Have something to do with it? via /r/wow https://ift.tt/j6te1Qd
